摘要： A continuous time digital signal processing (CT DSP) token includes a first signal indicating a change has occurred and a second signal indicating a direction of the change. An amplitude generation circuit operates to generate an amplitude value x in response to the token. A power estimation circuit processes the amplitude value x to generate a digital power signal in accordance with the formula: x2±2x+1.

摘要： A phonon parametric oscillator is provided. The phonon parametric oscillator comprises a laser for periodically emitting brief optical pulses (IL), an assembly for generating acoustic pulses (IA) and a medium for coupling the acoustic pulses to an object (O), the assembly for generating acoustic pulses comprising an entrance face, an exit face, a conversion medium for converting the brief optical pulses into acoustic pulses and a propagation medium for propagating said acoustic pulses, the entrance and exit faces being reflective to the acoustic pulses, the propagation medium having a defined thickness, the exit face making contact with the coupling medium. In the phonon parametric oscillator according to the invention, the round-trip time of an acoustic pulse due to reflection from the entrance and exit faces, is equal to the emission period (τ) of the laser, so that the reflected acoustic pulse is in phase with the following acoustic pulse.

摘要： An optical sensor, especially an artificial retina, that includes at least one photosensitive cell. Each cell includes a integration capacitor, a read circuit the operation of which depends on the charge of the integration capacitor, at least one MOS transistor operating subthreshold, and the drain-source current of which influences the charge on the integration capacitor, and at least one photodiode operating in photovoltaic mode and connected to the gate of this transistor, such that the drain-source current of the MOS transistor depends on the optical power received by the photodiode.
